flu/entanform a further function'in preventing the lifting of thecar-body when the safety or track brake is used, as will be explainedlater.

The two-wheel truck is built u pon substantially the same constructiveprinciples.

before described. In this dase,'however, I'

prefer to employ but one set of guard-wheels c for the truck. Theseinstead of being carried on extensions of the axles c or studsprojecting from the axle-block b are carried on a central crossbar e,secured across the frame I), as shown in Fig. 4. The guide-framed andguide-rollers d are in this case unnecessary, as the secondbearing-wheel performs their functions.

. To control thespeed or effect: stoppage the car, I prefer to employ atrack-brake of the following construction: Two "bell-crank levers f arepivoted, preferably, upon the axle c at opposite sides, respectively, ofthe main bearing-wheel C. At their lower terminals they are secured to ametallic shoe 8,

adapted to bear upon the track. The upper terminals of the levers areconnected by rods 9 witha hand-lever L, pivoted to acleat m, attached tothe rear of the frame-b. There is thus formeda drag, in which the shoe 8is hung from the axle of the bearing-wheel and operated by thehand-lever L. It will be seen that the effective limit of the shoe fric--tion would under ordinary circumstances be the weight of the car, butin this case the guard-wheels prevent lifting of the car, and the shoemay therefore be brought to bear against the track,with any forcedesired.

The brake may be made double,as indicated The annular wheel-frame islengthened to accomby dotted lines in Fig. 5, so as to operatein eitherdirection. a

I may employ both single and double wheel trucks together in trains oftwo or more cars, as indicated in Fig. 8. I

I do not claim in this application the brake mech'l'tirism herein shownand described, as the same forms the subject-matter of a separateapplication filed by me on the 21st day of February, I901, Serial No.48,223.

I claim as my invention and desire to secure by Letters Patent of theUnited States- 1. A car-wheel truck embodying an annular frame, adaptedto a swiveling or pivotal aoiion in relation to the car-body, one ormore double-flanged bearing-wheels journaled diametrically in the same,and fixe'd studs extending outwardly at opposite sides carryingguard-wheels adapted to run beneath guardrails, substantially as setforth.

2. A car-wheel truck embodying incombination, first, a frame adaptedto;,a swiveling or meted action in relation to the? car-body; second, abearing-wheel journaled diametrically in said frame, adapted to supportthe load upon the running-track; third, wheels carried at opposite sidesof the truck, and adapted to run beneath guard-rails; 'fourth, a rigidextension ofthe truck-frame; and, fifth, guidewheels carried upon saidextension and adapted to bear laterallyagainst the guard-rails.

3. In a single-rail railway system, a truck embodying anannular frame,two bearing- Wheels journaled within and across the same at oppositeends, and a central bar secured to the frame centrally between andparallel with the wheel axles, and carrying the guardwheels at itsextremities, substantially as set forth. l

In testimony whereof I have hereunto set .1
